SBS 2011 android clients sync not working

Dear experts,

I have a problem with ActiveSync. Some users complains their callendars and contacts do not sync with Android 2.3. Email sync works on affected phones.

When I setup new phone, sync works fine both directions.

I found this error on our SBS 2011 ID 1040 - MSExchange ActiveSync, see attachment.

No 3rd party firewall on our server, just Windows firewall.
I did a server restart, did not help.

Any suggestions?

Jarda

This is referring to your perimeter firewall. What are you using on the edge of your network to pass the traffic to your server?

Hello Spartan_1337,
I use Mikrotik 450G. It leaves session 1 day.
Maybe the problém with synchronization is not related with error 1040 (MSExchange ActiveSync).

Is it set for both HTTP and HTTPS (80 and 443)

It is only a warning but if your users are complaining, then this might be the issue.
If you run a test of your AS from here, does it all pass cleanly:

Yes, it is set for 80 and 443.

I ran a testexchangeconnectivity.com, the only error is self signed certificate. It should not be problem since other users are OK.

Certainly thank you for your effort. I'm trying to figure it out for 3 hours :(

If I try to recreate Exchange account on Android 2.3.6, I get "the server requires security features your phone does not support" error.

I turned off "require password" but it did not help.

Any suggestions?

Can you check you policy and see if you enabled "device encryption"?
This android OS is very old and there are plenty of issues with AS. Any option to upgrade as later versions do have better support for AS.

no, encryption is not enabled in default AS policy. I hope to figure it out without changing phones since they are 9 months old.

Can you post your AS policy and can you see the whole error on the phone?
There should be something at the end of that string that should detail what exactly is failing.
Do you see this phone still attached to the account? If so, remove it so it can download the new policy.

I created new AS policy and assigned it to a user. Then I removed old Exchange account, deleted all mobile phones from users properties in Exchange.

New AS policy is:
general - Allow non-provisionable devices
password - not checked
sync settings - allow direct push when roaming, allow HTML formatted email, allow attachments to be download
device - allow all
device apps - allow all

still "the server requires security features your phone does not support"

it seems that the problem has no solution: (

If I edited Exchange account on Android, it did not work. When I deleted Exchange account form Android and then recreated, it works.
